Description

  The present invention relates to a software component search system, method, program, and storage medium, and in particular, a software component search system, method, program, and storage medium that can accurately find a software component that a user seeks using an information processing apparatus. About.

  An example of a conventional software component search system is described in Patent Document 1 below. As shown in FIG. 10, this conventional software component search system includes a software component search system (1001), an input device (1002), an output device (1003), a storage means (1004), and a search means (1005). ) And a storage device (1006).

  The conventional software search method having such a configuration operates as follows. The storage means (1004) stores, in the storage device (1006), a set of a software component input as stored data from the input device (1002) and metadata representing the characteristics of the software component. The search means (1005) searches for metadata matching the metadata input as a search condition from the input device (1003) from all the metadata stored in the storage device (1006). The retrieval means (1005) acquires a software component that is a metadata pair in the storage device (1006) that matches the metadata inputted as a retrieval condition from the input device (1003), and outputs it to the output device (1003) To do.

  It is necessary for the user himself / herself to check whether the software component searched by the conventional software component search method operating as described above is a component requested by the user.

  In the confirmation work, the usage is confirmed by documents such as manuals, and the actual evaluation is performed to confirm the operation. When there are a plurality of similar parts in the software part group, in order to find the most suitable part, it is necessary to perform a confirmation operation separately for all the parts.

JP 2005-71221 A

  The software parts found by the conventional software parts search method need to be confirmed by the user himself / herself to see if the quality required by the user is satisfied, and the man-hours required for this confirmation work are similar software parts in the software part repository. The problem of increasing in proportion to the number arises.

  Even if the software component provider evaluates the component, attaches the evaluation result as software component information, and performs the evaluation items designed and created by the provider, the quality evaluation is obtained. It is impossible to judge whether the quality as the evaluation result satisfies the quality required by the user.

  In other words, there is no quantitative and accurate indicator of the quality level guaranteed by the evaluation items implemented by the parts provider and the quality level required by the user, and the user must confirm the details of the evaluation items implemented. For example, the quality level guaranteed by the evaluation item cannot be determined.

  Furthermore, the evaluation performed to guarantee the quality of the software component is an evaluation of the specification considered by the component provider, and does not necessarily guarantee the quality of the specification required by the component user. It is difficult to fill in the difference in specifications that occur between the user and the component user, and as a result, the above confirmation work is indispensable.

  However, it is very difficult to confirm all the details of the evaluation items implemented by the provider. Therefore, in the conventional method, it is necessary to evaluate the software component acquired by the user by the search by the user himself / herself.

  As described above, the cost for the confirmation process for confirming the quality of the acquired software component is high, and the cost increases in proportion to the number of similar components found by the search.

  The candidate retrieval means (105) retrieves software components stored in the storage device (106) based on the retrieval input definition given by the user through the input device (102) and the retrieval output definition.

  The candidate search means (105) stores the software component found by the search in the software component candidate storage unit (107).

  The evaluation item execution means (108) sequentially extracts all the software components stored in the software candidate storage unit (107) and operates them one by one on the execution environment (109).

The evaluation item execution means (109) evaluates all the evaluation items according to the evaluation item table given by the user for the software components operating in the execution environment (109), and reports the evaluation results. Data is created and stored in the evaluation result storage unit (110).

  Next, referring to the flowcharts of FIGS. 1, 7, 8, and 9, and FIGS. 4, 5, and 6, the operation of the software component search system according to the first embodiment of the present invention is described. Will be described in detail.

  The software component provider inputs a software component to be stored, a component input definition for the software component, and a component output definition for the software component to the input device (102) as storage components.

  The storage means (104) stores the software component, the component input definition, and the component output definition given from the software component provider through the input device (102) in the storage device (106).

  The user describes the functional specifications required by the user in the evaluation item table, the search input definition, and the search output definition, and describes the desired quality level in the evaluation result condition.

The user inputs the described evaluation item table, search input definition, search output definition, and evaluation result condition as search conditions in the input device (102).

  The candidate search means (105) receives a search input definition and a search output definition given from the user through the input device (102).

  Referring to FIG. 4, the candidate search means (105) sequentially acquires the component input definition and the component output definition that are paired with all the software components stored in the storage device (106) (step F11 and step F13), if the acquired component input definition and search input definition completely match (step F12), and the search output definition is completely included in the acquired component output definition (step F14), the acquired component input definition And the software component corresponding to the component output definition are acquired from the storage device (102), and the acquired software component is stored in the software component candidate storage unit (step F15).

  Referring to FIG. 5, the evaluation item execution means (108) sequentially retrieves all software components stored in the software candidate storage unit (107) (step F21) and loads them one by one on the execution environment (109). (Step F22).

  The evaluation item execution means (109) inputs the input data described in the evaluation item table given by the user to the software component operated on the execution environment (109) and obtains it. If the output output matches the output data described in the evaluation item table, the evaluation item is considered to have passed, and if it does not match, it is considered to have failed (step F23).

However, the input data described in the evaluation item table does not limit which input of the software component. For example, the evaluation item table describes 3, 4, “+”, and the software component has a method such as int calc (int a, String o, int b). At this time, “+”, which is a String, is uniquely assigned to String o, but 3 and 4 are not determined to be assigned to int a or int b. Therefore, in the process of step F23, all combinations to which the input data can be assigned are evaluated, and the result of the combination that has passed is set as the result of the evaluation item. In other words, in the case of the above example, both calc (3, “+”, 4) and calc (4, “+”, 3) are evaluated, and the evaluation result is output data described in the evaluation item table. If it matches, the result of the evaluation item is accepted.

  Pass / fail when the evaluation described in each evaluation item is performed is described in the evaluation result report data (step F24). The created evaluation result report data is stored in the evaluation result storage unit (110) (step F25).

Referring to FIG. 6, the evaluation result verification means (111) sequentially extracts all evaluation result report data stored in the evaluation result storage unit (110) (step F31) and is described in the evaluation result report data. It is confirmed whether the evaluation result satisfies the evaluation result condition input by the user (step F32).

  For example, when the evaluation result condition as shown in the figure is input from the user, the condition that the evaluation result report data satisfies the evaluation result condition is “the pass / fail item described in the evaluation result report data is acceptable, and the evaluation result The total number of columns in which the execution time of the report data is shorter than the execution time of the evaluation result condition and the I / O count of the evaluation result report data is smaller than the I / O count of the evaluation result condition is Number of items) × (allowable pass rate described in evaluation result condition / 100) ”.

  When the evaluation result report data satisfies the evaluation result condition, the combination data of the evaluation result report data and the software component paired with the evaluation result report data is stored in the evaluation result list (evaluation result table) (step F33). When the verification of step F32 is completed for all the evaluation result report data, the evaluation result verification means (109) sets all the evaluation result report data stored in the evaluation result list and the software components that are paired with the evaluation result report data. Are output to the output device (103) (step F35).

  According to the software component search system according to the present embodiment, the user can clearly express the desired specification by designating input / output and evaluation items. By selecting software components based on input / output and evaluation, the finally provided software components satisfy the specified specifications. In addition, by specifying the result tolerance, you can specify the level of quality of the software part and refer to the resulting evaluation report to modify the part to pass the rejected items. Now you can get software parts that meet all the specifications your users are looking for.
